Golog
Minimal overhead leveled logging routines for golang.
Introduction
Wraps log into a higher level abstraction that handles the following:
- Log levels
- File output
- Syslog output
- Performance timings
The goals of Golog are to get as close as possible to zero overhead, while allowing fine grained control of logging.
Dependencies
This package has no external dependencies.
Installation
go get github/mlavergn/golog
Examples
import . "golog"
SetLogLevel(LOG_ALL)
LogDebug("debug")
LogInfo("info")
LogWarn("warning")
LogError("error")
LogConfigure(LOG_WARN, LOG_STDOUT)
LogDebug("debug")
LogInfo("info")
LogWarn("warning")
LogError("error")

var LogErrorf _outputf = _Outputf
LogErrorf accepts a format mask and a value, outputting when LOG_LEVEL <= LOG_ERROR
var LogFatal _output = _OutputExit
LogFatal accepts a value, outputting when LOG_LEVEL <= LOG_FATAL, then exitting
var LogFatalf _outputf = _OutputExitf
LogFatalf accepts a format mask and a value, outputting when LOG_LEVEL <= LOG_FATAL, then exitting
var LogInfo _output = _Output
LogInfo accepts a value, outputting when LOG_LEVEL <= LOG_INFO
var LogInfof _outputf = _Outputf
LogInfof accepts a format mask and a value, outputting when LOG_LEVEL <= LOG_INFO
var LogWarn _output = _Output
LogWarn accepts a value, outputting when LOG_LEVEL <= LOG_WARN
var LogWarnf _outputf = _Outputf
LogWarnf accepts a format mask and a value, outputting when LOG_LEVEL <= LOG_WARN
